Noticeable improvement in plants
This is a very easy to use product. You just measure out the powder with the enclosed scoop and add to the watering can. Just a week or so after first use I can already see a noticeable effect. Plants are fully, look healthier and have many more leaves and blooms. No real negatives I can see so far. Good product.

New leaves on our tree…at last!
We weren’t sure our poor young Meyer lemon tree was going to survive. We’d planted it in full sun, watered it regularly, and had been using a different citrus fertilizer applied to the soil, but it didn’t have many leaves, and the leaves it did have kept turning yellow and falling off. I had never used a foliar fertilizer before and thought I’d give Jack’s a try as my last resort. I’ve been feeding our tree with this fertilizer for about 4 months now, 2 Tbsp. in 2 gallons of water in my watering can, applied to the leaves every Friday, with the excess falling onto the soil around the tree. And our tree is looking healthy again, with lots of new leaves and more tiny ones sprouting out! What a joy to see! (And a relief not to have to replace a $200 tree!). Highly recommended!

Great product
My orange trees love this fertilizer. A friend said they had never seen so many blossoms on an orange tree.

Good quality plant food.
This product provides vibrance to trees and plants when applied correctly. Leaves become noticeably greener when the trees and plants had sufficiently absorbed the fertilizer.

Great size , goes a long way.
Great product, easy to mix, and works well to perk up the leaves.

Love this stuff!
I fed this to my container dwarf lemon tree for its first 2 years and it did wonders! It produced about 12 lemons in that time frame. Over the holidays I had misplaced the fertilizer and it unfortunately wasn’t fertilized for about 4-5 months. I thought that I had lost my little tree! I bought some more of this again in effort to save it and have been consistently been using it 1-2 times a week for just over a month. In that month, new leaves have grown in and tons of blossoms have returned! I love this stuff and so does my little lemon tree!

I had my lemon tree, which I started from seed several years ago and found that it grew ok but needed some help. Some of the leaves were turning yellow, but the tree was reasonably healthy. So I decided to try the Jacks formula and was pleasantly surprised that the leaves were slowly getting a richer more vibrant green. I started with a weaker solution at first, and gradually increased its dosage. So far the tree is looking far better than it did before. I will certainly buy more when I run out - which should take some time. I would recommend this product.

Just 2 applications to my lemons and oranges and the leaf size doubled for the new growths. Expensive but application is just 1 spoon in around 4 litres of water in 7 to 10 days. So it will last a long time.

The micronutrients is the key to successful citrus fruit trees. This has it, and my orange trees love it! They look so much better since I used it.

Too soon to really tell how effective this product fully is but as a foliar spray goes, it works. Within a few days the leaves went from having some yellowing to a full vibrant green color!! Time will only tell on the effectiveness of the growth of the grapefruit tree I'm using this product on. If it does, this product will go from a four star rating to a five star rating from me and from what I have seen so far, I have high hopes and confidence it will be a five star product!
